What's the best advice if you know someone that's in the dacco treatment,but still using meth and Xanax undercover, because the person know they only get drug tested once a month,and can keep getting high after testing?

I usually don't comment on stuff but i would say focus on your own sobriety. Let them be their own keeper. It's not okay to interfere with someone's medical situation and if they are doing wrong it'll catch up to them in time but to interfere with someone else's situation could backfire on their treatment and actually push them into a really bad situation.
